Abstract

A blow molded plastic container is provided. The container has a body section having a substantially non-circular cross-sectional shape, the body section having an enclosed bottom portion that forms a bottom end of the container and substantially flat side portions extending upwardly from the bottom end; a finish defining an opening; and a dome extending from the body section to the finish. The dome includes at least one stiffening structure formed by an inwardly indented, vertically extending groove.

First claim

What is claimed is:

1. A container, comprising:
a body section having a non-circular cross-sectional shape in plan view, the body section having a bottom end and sidewall portions extending upwardly from the bottom end;
a dome extending upwardly from the body section opposite the bottom end; and
a finish extending from the dome and defining an opening;
wherein the dome includes a plurality of dome face portions defining corners in plan view, each dome face portion including a concave region in side view proximate the body section and a convex region in side view between the concave region and the finish, each dome face portion further including a panel proximate the body section;
the dome further including at least one stiffening structure formed by an inwardly-indented, vertically-extending groove at each corner of the dome.

2. The container of claim 1 , wherein each inwardly-indented vertically-extending groove is concave in cross section.

3. The container of claim 2 , wherein each inwardly-indented, vertically-extending groove is V-shaped when viewed from a top view orientation of the container.

4. The container of claim 1 , wherein each inwardly-indented, vertically-extending groove extends across at least a portion of the convex region and at least a portion of the concave region.

5. The container of claim 1 , wherein the at least one stiffening structure increases top loading strength of the dome.

6. The container of claim 1 , wherein the plurality of dome face portions comprise at least one oppositely facing pair of dome face portions and at least one oppositely facing pair of dome end portions.

7. The container of claim 6 , wherein the dome is substantially rectangular in cross-sectional plan view.

8. The container of claim 1 , wherein at least one panel has an indented formation defined therein.

9. The container of claim 8 , wherein at least one of the panel or indented formation defines a grip.

10. The container of claim 8 , wherein the indented formation includes a stiffening rib.

11. The container of claim 1 , wherein the body section is substantially rectangular in cross-section.

12. The container of claim 1 , wherein the body section includes at least one horizontally-oriented, inwardly-indented stiffening rib.

13. The container of claim 1 , wherein the bottom end includes a push-up base.

14. The container of claim 1 , wherein the dome further includes at least one vertically aligned area relative the bottom end.

15. The container of claim 14 , wherein the at least one vertically aligned area is indented.

16. The container of claim 14 , wherein the at least one vertically aligned area is raised.
